INSTALL CAMSHAFT
| *1 | No. 1 Valve Rocker Arm Sub-assembly |
| *2 | Valve Lash Adjuster Assembly |
| *3 | Valve Stem Cap |
Make sure that the No. 1 valve rocker arm sub-assembly is installed as shown in the illustration.
Clean the camshaft journals.
Apply a light coat of engine oil to the camshaft journals, camshaft housing sub-assembly and camshaft bearing caps.
| *a | Knock Pin |
| *b | Approximately 17° |
Install the camshaft to the camshaft housing sub-assembly as shown in the illustration.
INSTALL CAMSHAFT BEARING CAP
Confirm the marks and numbers on the No. 1 camshaft bearing cap, No. 2 camshaft bearing cap and 3 No. 3 camshaft bearing caps and place them in their proper positions and directions.
Uniformly tighten the 10 bolts in several steps in the order shown in the illustration.
Uniformly tighten the 11 bolts in several steps in the order shown in the illustration.
Check the torque of each bolt again.
INSTALL CAMSHAFT TIMING GEAR ASSEMBLY
| *a | Advanced Position |
| *b | Retarded Position |
| *c | Alignment Mark |
| *d | Knock Pin Hole |
Check the camshaft timing gear assembly position.
Note
If the camshaft timing gear assembly is set to the advanced position, do not let the camshaft timing gear assembly rotate clockwise during installation.
If the camshaft timing gear assembly has rotated to the most retarded position, make sure to release the lock pin and set the camshaft timing gear assembly to the most advanced position before tightening the bolt of the camshaft timing gear assembly.
| *a | Narrow |
| *b | Wide |
Install the camshaft timing gear assembly as shown in the illustration.
| *a | Narrow |
| *b | Wide |
Turn the camshaft timing gear assembly approximately 180° counterclockwise.
| *a | Paint Mark |
| *b | Timing Mark |
Align the paint mark with the timing mark and install the chain sub-assembly to the camshaft timing gear assembly.
Tech Tips
"A" is not a timing mark.
| *a | Knock Pin |
| *b | Knock Pin Hole |
Align and fit the knock pin of the camshaft with the knock pin hole of the camshaft timing gear assembly.
| *1 | Camshaft Timing Gear Assembly |
| *2 | Camshaft Flange |
| *a | Incorrect |
| *b | Correct |
| *c | Gap |
| *d | No Gap |
Check that there is no gap between the camshaft timing gear assembly and camshaft flange.
Secure the camshaft in place by hand, and then install the bolt of the camshaft timing gear assembly by hand.
Note
Do not use any tools to install the bolt. If the bolt is installed using a tool, the lock pin will be damaged.
If the lock pin has not been released, release it.
| *a | Make a Hole |
| *b | Adhesive Tape Sealing Area |
After cleaning the intake side VVT oil hole on the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.
Note
Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.
Make a hole in the adhesive tape covering the oil hole as shown in the illustration. (Procedure A)
Apply approximately 200 kPa (2.0 kgf/ cm2, 29 psi) of air pressure to the hole made in procedure A to release the lock pin.
Note
If air leaks out, reattach the adhesive tape.
Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.
Forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).
Tech Tips
Depending on the air pressure applied, the camshaft timing gear assembly may turn in the advance direction without assistance by hand.
If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.
Remove the adhesive tape from the No. 1 camshaft bearing cap.
| *a | Hold |
| *b | Turn |
Using a wrench to hold the hexagonal portion of the camshaft, install the bolt.
Note
Be careful not to damage the cylinder head sub-assembly or spark plug tube with the wrench.
| *a | Paint Mark |
| *b | Timing Mark |
Check that both timing marks on the camshaft timing gear assembly and camshaft timing exhaust gear assembly are facing upward as shown in the illustration.
Tech Tips
"A" is not a timing mark.
